Just another note to respect the "thread drift." The GP100 is a nice revolver, but it took some work to get it there for me. My 617 was great out of the box. As mentioned above, the 617 was my first handgun. The only thing I didn't like about it was the underlug -- and my objections had nothing do to with function. I just never liked the look of the thing, and it isn't as if a .22 LR round produces a ton of muzzle rise. I was actually mid-way through a conversation with my smith about grinding the underlug off, and he said, "Why don't you just get the Ruger GP100? Instead of destroying the resale value of your 617, you can shoot a similar revolver that was designed
without the underlug." So that's the route I went, because my smith is smarter than me about handguns.
Well the GP100 arrived and there were two problems I noticed right away. The first was that the revolver wasn't correctly timed. It was spitting lead back at the shooter and the accuracy was not that great. Also the trigger was heavy and gritty. Ruger uses CNC machining to put together their pistols. Are far as I know they are tested for fire function only. There is no polishing or handfitting. Put 'em together, and get 'em out the door. So the Ruger went back to the NH mothership the day after its first range trip for correction to the timing. Ruger clearly spends their bux on customer service, not QC out the door -- not disparaging, just observing. My pistol should have never been sold to a member of the shooting public in its original condition. That said, they turned it around quickly and solved the problem. Great customer service, as I said. Not quite enough to save the "first day at the range" experience, but that's another matter. The triggers on these things are a brilliant design. Removal of the entire group was almost tool-less (you need a screw driver, and that's about it) and polishing the mating surfaces with an Arkansas stone and some oil did not take long. I was a bit surprised that it needed it. After all the 617 just worked great right out of the box. But if you don't mind the extra elbow grease, you might overlook the quality of the Ruger triggers. It probably would have slicked up on its own after a couple of thousand rounds . . . but still.
After all that, the S&W still does better, group wise off a bench. Is that important if you are shooting steel? I don't know, only you can answer that question. My GP100 also has an odd "ping" vibration on each shot. I have no idea what causes it, but it is a bit distracting if you are following through on a slow fire course of fire. Here's my current set up with the GP100 and some typical 15 yard rested groups.
Here's my 617 (on the bottom) and a typical set of its 15 yard groups (BTW, those are eight consecutive 15 yard groups off an MTM rest with no cleaning or pause between them (e.g. not cherry picked like that target right above this text). What I am saying is that the 617 prodced these groups with different ammo one after the other, and it is what I have come to expect from the revolver):
Finally, I did go back to the Single Six format eventually. I got a "Bilsley" Single Six, which I tricked out this way:
This pistol also came from Ruger with a problem out of the box. I think one of the cylinders wasn't drilled true. Either that, or it was my old friend "timing problem" back for another go. Here's the Whiskey-Tango-Foxtrot target from
that first day out:
As you can see, off a rest at 15 yards, one cylinder chamber was consistently shooting about 3-4 inches to the left.
I am not saying that S&W doesn't occasionally goof up, but my own experience with them has been of a "get it right the first time" variety. Ruger's very efficient customer service made the Single Six function properly, but I don't have the sense that they particularly mind if their customers have experience after experience along the same lines. FWIW, I never had a problem with any of Ruger's .22 semi-autos, so it isn't like they don't know how to produce a gun that works first-time, every-time. It's just that in my experience with their revolvers, you have to be prepared for a bit more process than perhaps you'd like. Not saying they won't make it right eventually. But I have the uneasy feeling that I have been turned into Ruger's unpaid QC division on its wheelgun sales.
Hope this helps.
